Exceptions

Django Rest framework brings all the package when it comes to validations but sometimes there is a need to have something more unique and granular.

ValidationException

The application on any level (view, model, serializer) can raise an exception similar to APIException but with the possibility of providing different status_code and message details.

How to use

...
from django_fast_utils.exceptions import ValidationException

class MyView(APIView):

    def get(self, request, *args, **kwargs):
        try:
            user = User.objects.get(pk=1)
        except User.DoesNotExist:
            raise ValidationException(
                "User does not exist.",
                status_code=200
            )
